One other option- it may be outside your budget, but the pads themselves are very good. Try Hart Dynamics. Their web site is
http://www.hartdynamics.com and they have a retail outlet under the same roof called
http://www.edrumstore.com .
They occasionally have killer sales on equipment, which is how I picked up my Hart kit a while back (for less than half of the old V-Pro price). I use it with
a Roland TD10 brain. The Alesis kit you see at retail these days is actually OEM Hart pads with the Alesis logo on them... I have played and broken the Roland hardware, and the Yamaha hardware looked equally dodgy (for a heavy player like me). The Hart stuff has held up unbelieveably well, and I very much like the Hart cymbal feel: I don't like to have to think about whether I'm playing acoustics or E-drums. On a tight budget, I'd spend some time looking for used Hart pads and then snag whatever brain suits your sonic needs.
Drummers can be very hard on equipment, and underbuying can be more expensive in the long run than saving up and just getting stuff that really matches your needs right up front. Breaking equipment gets expensive. Trust me- I bought
a Roland TD7 kit, killed most of the pads, replaced them, killed the replacements, replaced them with Pintech pieces and killed _them_ before I found the Harts. My pocketbook still smarts from that exercise.
There are many threads on
the Roland VDrum site having to do with this theme. It would appear that I am not the only one who plays hard and gets tired of replacing broken hardware, clamps, and pads. That site also has a listing for classified ads for used equipment, where you might find some useful leads. That is
http://www.vdrums.com .
Just a thought: your mileage may vary, and you may be a very light player so that this doesn't apply. Still, IMHO, they are worth a look.
