Really a suck it & see approach. I don't have the funds to get my preferred Tamron 90.

Well I am sure you have seen my posts with the helios and jupiter 9 + raynox 250.
And I think the combo can do almost as good of a job as my dedicated macros. But if you look at those posts you also see that like with ext. tubes, the DOF is really shallow with the raynox too.
Here is that Helios thread... some of those shots have quite a bit of cropping
But check out the razor thin DOF...

And the Jupiter 9 thread

You can get the the shots with combo, but like with all moving macro shots you throw away a lot more than you post
Even with a dedicated macro lens like the tam 90 (which is a lens I have always wanted)... stopping way down to F18/22 and using a flash will help with the DOF.
The pro's use a really nice macro flash system and a trick called focus bracketing. Way above my limited money/skills.
Flash is your friend... Cropping is your close-up buddy...
As I have mentioned before the Raynox 150 is a little easier to use only because of the less magnification and more DOF. But with the 58 and 85mm primes it makes sense to go for the 250 if you want really close up shots.
good luck
