I love my Manners T4a and now Manners have folders that have the adjustable cheeks. But I they start to get pricy and will either need bedded and a dbm or add the mini chassis on. Or you can look into the XLR chassis, they have adjustable cheeks and can add a folding mechanism also don't need a dbm.
Or look at the Mcrees chassis, folding, adjustable, built in dbm and less expensive than the others I mentioned for the same features. Also, I believe they have little to no wait whereas I think XLR has a decent wait as does Manners.
