Yamaha DTXpress/DTXplorer/DTXtreme

Hello,

I'm fairly new to electronic drums and was wondering if anyone could
shed some light on this dilemma I'm having.  I pretty much had my
heart set on a DTX3SP until recently I saw some amazing prices on the
Pintech Studio Elite Kits (2003 ed). Seems I can have both the Pintech
and an Alesis DM Pro drum modual for < 1k. Can anyone with experience
comment on the  pros/cons of these kits vs each other? Especially in
terms of playability and sound quality. The quality of the pintech
snare and toms seems to be a big plus, but the hi-hat does not look as
nice. So, is it easy to set up Pintech kits with the DMPro? Would I
still have all the playability and expressiveness of a DTX3SP?

Thanks for your advice,
Ken
