Welcome to geekhack!
The question is, where are you? If you're in the US, you can often find a nice quality 1391401 on ebay with 2 piece keycaps.
I'm a big buckling spring and topre fan, personally. You can't really go wrong with a Customizer. For a small fee, they will even modify the layout, if you desire.
You'll have a hard time finding a Filco right now (at least in the US). You could try the Noppoo Choc Mini, or one of the Ducky boards, though. Roughly equivalent to the Filco.
And just in case, don't forget that Das has a student discount. Not sure if you are one, but thought I'd mention it. They don't really advertise it.
But, it really depends on where you are, and what you want. If you like the blues, but think they are a bit light, you'll probably like the buckling springs. If you are willing to spend the money, you can't go wrong with a Realforce or a HHKB.
And keep in mind, you can usually sell anything you don't like here in the classifieds section.
