I'm looking to buy, rent or borrow a valve spring compression tool for my 1980 Honda CBX 1000. I have heard that the "universal" spring tools can cause expensive damage to the CBX.
Any leads?

out with a socket, in with the tool.
taking vales out - this is not nice but actually worked OK.
I took the head to some bike friends that have an import auto shop. They showed me how to tape up a deep socket (electrical tape) to prevent scratching. They supported the valve so it didn't come out and bend (a rag folded over underneath for firm support) and hit the socket on the top of the valve spring sharply but not really hard. I raised my eyebrows on this but they have done it a zillion times without harm on many expensive engines. The colletts just pop out and the valve is free. It worked fine and I did the rest of them.
A compressor would be much politer. I too will have to find, make or get one for assembly someday.

Removing Valves
No -- do NOT remove valves by banging on a socket. The stems are frequently damaged. that way. Besides, you still need a spring compressor to reinstall them. The Honda one is universal, but there is a special tool that fits down into the lifter bore to shield the walls of the bore from scratches that would otherwise be made by the tool.

I actually agree with you Mike; this is a bad idea unless you don't care about risking the valves being damaged. I didn't.

Valve Spring Removal
Not to belabor the point, but in the best shops, a tech who removes valves that way is sent packing. 
The special tool (page 6-12 of 81/82 manual) is part number 07999-4220000, though I am sure a suitably sized thin-wall sleeve of metal or similar material would work well (all the tool is, is a sleeve with a lip to prevent its falling into the spring hole).
