If all you EVER will do is rocket parts the bench top saw will be "OK". The Pro-Tech or Tool Shop brand 9" saw that Menards sells is pretty much identical to the Ryobi. I bought this and once it's tuned they work fine. The blade speed is too fast for metal work though. However, since then I've also gotten into woodworking and kick myself repeatedly for not saving up and buying a real band saw, like a 14" Jet, Grizzly or Delta.
No matter what size you get, get cool blocks to replace the hardened steel guide jaws that come with the saw. I got the small 1/8" square ones at Menards. If you even just kiss the blade teeth with the hardened blocks you'll ruin the blade at worst and mess up the tooth kerf and cause it to not cut straight at best. The cool blocks are soft wear resistance material and you can bury the blade, teeth and all, right into the guide blocks. They make for much straighter cutting.
In response to another later inquiry: I've found it's best to get name brand power tools. They cost more but you do get more. Sometimes the bargin brands (like Harbor Freight) are OK but you need to look into what your really getting. (I've got a little electric hand sander that is really great) Just because it's made in China does not mean it's automatically junk. Jet Grizzly and much of the Delta line are all made in China and/or Taiwan and they certainly aren't junk. I often wonder if some of the the Harbor Freight tools are the QC rejects from these :-)
If you get a drill press get a floor model or the largest bench model you can find with the most HP, speed ranges and SPINDLE STROKE. The off brand bench top presses don't have alot of balls or capacity. Here again I kick myself for buying the small off brand bench top model and will soon be investing in a real drill press.
Table saw is overkill for rockets I'd think, unless they're really big. But, if you do any woodworking at all it's the foundation of the your shop. Don't skimp here if you think you may do any woodworking and expect to get straight precision cutting. I own a Jet 10" contractors TS and it is great. The direct drive table top models are only good for rough work IMO.
Bench top belt/disk sander is indispensible for G10 and ply and even balsa with finer grits. Great for sharpening you lawn mower blade with a 60 grit belt. Some off brand models are fine. Shop around. I don't know how I got along without mine.
More cast iron is good, really :-)
