What's a good digital machine?

Hey guys. I'm in the process of moving house. And the Mrs has agreed to let me have my own man cave. I already have a DOND fruit machine but I really fancy a digital one. I've noticed the T7 machines on ebay but this is the only machine i know of. I'm after something that I can use as a good piggy bank with various games. And more importantly something that is idiot proof so to speak. Is T7 my best option. I'm very new to this so I'm not familiar with much apart from i know the newer machines need a licence for real play which for me is a must.

Thanks
