As for some of the Lenzi's mentioned,i've already got 2 dvd's of Spasmo and 2 of Eyeball,ok I've only got 1 of Bloodstained Orchids...
As for Bava,imho the only one that's in need of a good re-release (longer oven scene?) is Blood and Black Lace,seems there are already enough good Bava dvd's available.
The neglected La Venere d'Ille could maybe also be an option?
With the German dvd of B&BL going for ridiculous sums of money and the US VCI dvd being poor,I suppose there is a market for a nice new dvd.
To be honest I prefer "first time on dvd" releases...but that's just my opinion.
