I love early Genesis too. So arse to the lot of you!
The remastered CD's from a few years back are a HUGE improvement over the first CD releases. To my mind, the Japanese 'mini LP CDs' are slightly better still (they are actually exactly the same remasters as the standard jewel case editions. Even so, the consensus is that they have the edge sonically. Don't understand how, but they just do!). Beware though, there are many counterfeits of these Japan CDs out there in eBay land. Genuine originals go for silly money.
