Yes they are very good toys. I own quite a few and have not been disappointed. The only problem, sort of, is the way they're sold.
The set you have there is an EX set, meaning it comes with the parts and accessories, but no body.You would either have to already have bought a full set, or buy a MMS naked body.
One other note, there are other MMS bodies sold, for example there's the Skygirls set of MMS bodies, which I thought I'd buy one to use for my EX sets. Unfortunatly the one I got has additional plastic on it which makes it impossible to attach certain piecies withought some serious cutting first though. But any body that is from Bouso Shinki and not another copyrighted series will be perfect for your EX sets.
I hope I've answered your question, if you have any other questions, ask away.
