Damn, talk about starting at the TOP OF THE HEAP!!!
The SP500 (and SP1000) are my favorite Spotties, I like the lack of self timer...
And that 35mm is I feel one of the best Takumars made.
Depending on what sort of shooting you like, here are a few bits I find useful:
- M42 extension tubes, you should be able to get a set for about $15. Takumars make for good macro lenses with a tube or two.
- a 55/1.8 lens. You can use one of these with the teleconverter, or of course on their own. Cheap and excellent.
- A cable release. In available darkness, you can put your camera on something and use the cable release. You can get a cheap self timer gadget for the cable release. You can get a cheap gorillapod/tripod/something.
- A red filter, or yellow-green, 49mm, for b&w shooting, to accentuate the clouds. And/or a polarizer - don't bother paying for a circular polarizer, the Spottie works well with the old linear one. Only thing, your 35mm lens will get dark with any dark filter on it...
- Oh yea, a lens shade for the 35. Mine came with a standard Vivitar rubber collapsible thing, which vignettes just a tad on 35mm film... so you'd be better off looking for a hood that works with the 35mm focal length.

But really, all the above is strictly optional. Just get some film and enjoy!
Congratulations, and welcome to the club.
