Tama does make a great kit and in my opinion, poplar is great wood for an early kit. Much like maple, but a little less overtone to worry about.
As for double pedals, I personally haven't tried the pdp's but I can thoroughly recomend the
sonor 400 series. I've been using them in both a single on two bass drum and double on one configuratoin and that is a great pedal for the price.
