Which DIY board(s)?

Hi guys, DIY amp noob, so please be gentle.

I would like to build a Class D power amp. 2ch, between 100-200wpc into 8ohm.

I'm looking for the best possible sound quality on a budget. Ideally I would like a decent ebay board(s) or are they a waste of time and Id be better of going for Hypex or similar? IRS2092 based?

Any nice kits that come with a credible PSU?

Your recommendations and guidance appreciated.
