I have heard good things about Melrose. I believe it's a frying pepper, similar to Jimmy Nardello, which is quite early and we love the taste as well.
A thicker walled early red sweet pepper with more of a bell shape is Franks. One unique thing about Franks, I have ripened the late ones to red off the vine in a paper bag without shrivelling up or turning nasty.
I'm not a fan of unripe peppers.
