Hi

This is my first posting, Hi everyone.

I'm looking for information on the availability of the SDX, SDE, MTM 
and Silicon Mallet and what prices they go for as I'm putting my kit 
back together after a bad split in which most of my gear was sold, 
smashed or lost. 

A few questions.
Is there a modern equivalent to the above?  I don't mean are there any 
newer electronic drumkits but is there anything that can do the job of 
an MTM for example?
How does the SDX rate agains newer kits?

Thanks
David
