It would seem that before just randomly buying anything, you'd think about what you'd like to experiment with first...
Me... I'd leave putters out (unless you're failing with your current one). If you have something that works, not much point in switching.
What distance are you looking to throw? <300 or >300. That'll shake out a few discs.
Do you have a larger or smaller hand. A lot of folks don't like the wider rim discs because of the size of their hand. If you haven't thrown one, it might be a reason to try one of them, just to see how they feel. That's a select group of discs.
How is your arm speed? Is it worth investing in some of the really super, duper fast discs if you're really not going to get the benefit from them? (Me, I answer yes, but I'm an addict and my game suffers because of it)
How do you feel about your midrange discs? If you're a Roc lover like so many folks around here, there really isn't any point in picking up discs that are covered by a Roc unless you surmise that if you like it better, you might pull the Roc out. I'm still struggling with trying to like the Roc more than my Wasps.
If you can figure out some of those, it might help you narrow down which type of discs you're really looking for and you might get a larger selection of the same discs -- this might indicate what the favorites are and give you more confidence in the purchase
For example, in my collection, probably 60% of my discs are of the super/high speed driver variety. I can throw them, but I'm not breaking 400' and I don't believe it's in my best interest to throw them at the moment. What I need are some of the older molds (eagle, teebird, etc.) to practice with and work up to the faster discs. Dunno if you have a hole in your collection (hopefully smaller) that you might want to fill or experiment with, but that's a suggestion too.
Sorry about the long post and no disc recommendations.
