Good thing about Spectors (and most other nice basses), don't look at it as potentially "wasting money". It will be a trivial resell if you decide you don't want it, and you'll at least get all of your money back. I like to think of it as moving money into an asset, knowing I'll never lose money on it. Now it's another thing altogether if you don't have the money to spare to being with, but moving a liquid asset into a non-liquid asset isn't much of a gamble in this case.
I just bought one of those Sire basses because I was curious, knowing I'd get all $500 back almost immediately if I hated it (turns out I quite like it though, so I'll keep it around). Prior to that, I bought a Ken Smith Black Tiger for a smoking good deal, knowing I'd probably profit about $1000 if I decided I hated it (which, you know, I didn't).
Anyway, some risks are risky, but I don't think that's particularly true in this case.
Or, if you ever find yourself in Atlanta, swing by and give mine a try.
