Yamaha DTXpress/DTXplorer/DTXtreme

Hi you guys,
 
I been learning for only a year now and my kit is too just loud for 
me to practice properly, neighbours, kids etc... I've been 
recommended a Yamaha electronic kit as a good method of learning 
quietly, but it's a lot of money even with trading in my old Premier 
kit. Can anyone out there give me some confidence that I'm doing the 
right thing. I want to play live eventually, but sooner rather than 
later.
