I used remastersys in the past, before I discovered Refracta. I don't want to criticise personally anybody who writes code that actually works and publishes it as GPL.
However I feel more comfortable with a community-orientated project (Refracta) which has Debian roots. That's not considered a "grind" at all.
I see no "********" going on here, no Ubuntu mentality, nobody throwing a public wobbler over their "intellectual property" and no plan to transfer it all to a corporate entity.

Just beware community projects can have their own problems when they become popular (ex-sidux user here)
