Ok..the next step is a flash....any recommendations?
I have been reading about ways of modifying the pop up flash so that it works better for macro (by putting plastic, cardboard, etc) but I am not sure if that is the best way to go. Would any cheap flash do?

The pTTL flash system on your camera won't work automagically with a reversed lens, nor with anything but auto-aperture (A- or F- or FA- or DA-type) lenses mounted normally. The pop-up flash generally sucks with macro anyway. I'll use a ringflash or some external flash with auto-aperture lenses, and ambient or controlled constant light with a reversed or other manual-aperture lens.

Non-pTTL flash *can* be (and is) used with manual-aperture lenses for macro work, but it's a bit tricky. I'm lazy; I just don't bother. One thing about "cheap flashes", especially older ones: They may have trigger voltages that can FRY YOUR CAMERA! I use such but I make sure they never touch nor connect to the camera. They sit atop cheap slave triggers on strategically-placed 'pods. Before buying any cheap flash, check that it's safe to use with your camera. Others here can tell you how to do that; I'm about ready to fall asleep. [/me head goes THUNK onto the table]

OK, I'm half-awake again, but not for long. Whatever flash you are thinking of, gargle for its name plus TRIGGER VOLTAGE. This information will keep you from bricking your camera.

[Bricking a camera: turning a camera into a brick.]

And/or get any old cheap (five bucks max) flash(es), and some rotten-cheap minipods, and some nice cheap slave triggers (about US$8 on eBay, shipped slowly) and arrange those around the poor dazed innocent subject. Use your pop-up flash to trigger those slave lights. Experiment with placement (camera, lights, subject) and exposure (speed, f-stop, camera and flash modes, ISO, filters) till you get it right.

[Filters: you may need some ND if the flashes are too bright.]

That should help. Now I think it's time to pull off my Chewbacca foot-warmers and crawl in. Zzzz...

do you think this flash should be fine?
I have read in the reviews that it can be used with the kx safely...:

I use the Metz 48 AF-1 both for macro and normal applications. I use a large (10x10) lumiquest diffuser that acts as a rather large softbox (for macro subjects) just above the lens. I typically set the magnification I want to shoot at and chimp in the exposure manually, because any bright specular highlights cause P-TTL to puke and die. After getting inexplicably underexposed images of shiny beetles, I figured this out. So if you set your magnification ( dial in the focus, set the flash power to properly expose test subject ) you have a point-and-shoot high-quality macro. You walk up on your subject 'til it's in focus, and start takin' pictures

disclaimer: I don't even know what "chimp" means, except that it seems to mean "evaluate your exposure or composition by real-world feedback (looking at the LCD) rather than abstract measurement".

Guys, do you think my M200 would be a good candidiate for this 'reverse lens macro' project??? Should I get a reverse ring and mount the ring and the the camera reversed and I'm good to go???

The lens will work, reversed. With an M lens (or anything but a DA) you have an aperture ring, so you can control the f-stops. Personally, I find 200mm a bit long for comfortable use, reversed. It's still a 200mm lens. Your working distance will be under 50mm / 2in. Your DOF will be very thin.

Mount-reversal rings are cheap, like around US$5, so experimentation won't be costly. And you could use that adapter with cheap step-rings, to reverse lenses with smaller front threads. I say, GO FOR IT!

The M 200 would be a fantastic lens for a stacked lens macro project

Good idea! Yeah, I forgot to mention that. With a cheap simple male-male thread-reversal ring, a 50mm secondary can be stacked on the 200mm primary for 4:1 magnification! Shoot the reflections on an ant's butt! Umm, be sure to use a tripod, eh?

Cheap manual 200's are cheap. Even good manual 200's are cheap.

One word: Microscope adapter. One more word: Lotsa macro tubes.
