I was going to wait until I get into a house, but I think house shopping is going to take a lot longer than I expected. (I live in an apartment.) And I have a little bit of money that isn't going towards the future house. So...
THE HECK WITH IT -- I'M BUYING THE REST OF MY KIT!!!

OK, putting all concerns about neighbors and practicality aside (I already have a game plan how I'll be able to practice and record with my full drum set), I have questions about what to look for.
Here's what my current kit consists of:
* Yamaha Anton Fig Signature Snare
* Sabian 14" Fast Hat
* Zildjian 16" Projection Crash
* Sabian B8 20" Medium Ride
I'm looking to buy a kick, two mounted toms, and a floor tom. I'll be recording mostly jangly guitar pop music, but I'd want a kit that's versatile enough to handle occasional jazz-influenced and rock stuff. I'll be using the kit primarily for recording in my studio. There won't be any live performances with this kit, other than informal jam sessions with friends.
The problem is, unlike the other components of my kit (where I had a pretty definite idea of the sound I wanted before I bought the component), I don't have any idea what I want for the rest of my kit.
It seems that kick drums all sound pretty similar to my ears, and when recording a kick in the studio, the kick can be manipulated to such a point (with blankets, pillows, and mic placement) that I wonder if it even matters which kind of kick I end up going for. (I know this
can't be true; that's just how it seems to me at the moment.)
Likewise, I'm not sure what to look for when listening to toms in a store. Should I be looking for something that has a nice sustain and minimum ringing from the other toms? I don't have a specific sound in mind; I just want something that records well and is versatile enough to work with different styles of music.
And then there's the question of hardware... How much of a difference does the hardware make?
One sales guy told me that the Perl Export EX was probably the kind of kit I was looking for... I'd like to hear other drummers' opinions and experiences. I'm looking to spend not much more than $600 for the kick, toms, and hardware (I don't need a kick pedal -- already have one). Is it realistic to expect a fairly good quality, versatile kit for that amount of money? Any suggestions and opinions would be greatly appreciated!
Thanks in advance...
