Got mine a secondhand Alesis Nitro Mesh... (Nitro over the Turbo as Head and Rim Snare, expandable and a tower bass drum, rather than a pedal switch £150...)
Then got a SH second tower for double bass drum £30ish... SH Tom 4 and SH Crash 2 at about £25 a go each... (you can get the Tom and Cymbal as an Expansion pack for £100)
He is really happy with it...
SH eKit but go with Mesh Heads...
