Honestly, if you get at least one chance a week to play on an acoustic set, i think getting an electronic kit shouldn't hurt your playing too much. i agree, try out stuff at yamaha and swee lee.
check your budget as well. it might do you well to save up for a better ekit. the other day i tried the DTXpress II (i think) and DTXtreme. i must say the DTXtreme impressed me, but the price tag is pretty high, and it's pretty large, unless the Xpress, which can be folded up. That said, you can make a lot more adjustments to it "kit-wise". Like the snare and hihat can be nicely adjusted since they're not part of the rack etc.
The pads on the Xpress are pretty small, but when you think about it, they help improve your accuracy, which will lead to a more consistent sound on an acoustic kit.
As for "silent kits" like the rhythm traveller - unless you have access to acoustic kits rather frequently, i would suggest getting electronic since you can HEAR what you play, and it's more satisfying. i myself have a rhythm traveller, and it's kinda sad when you can't really hear what you're playing.
