Depends really on your budget, and what gauge you want to load.
Years ago I borrowed a friends Lee Load-All 11 @ about £80-90 these days. It worked fine, and was cheap (about £45 back then). Commonly available for 12, 16 & 20g
Personally I use MEC 600 Jr Mk5 (got mine from Clay and Game) and have done so for about the last 10 years. Not routinely used it for 12ga clay loads (I have 12, 20 and .410 MEC variants) as until recently prices for 12g clay loads were bearable. Used it to help load 12g black powder loads as well (though you don't want to put BP through these). That said, given the possible impact of non-toxic load requirements, they may be an idea generally. I have a universal charge bar for the 12g version, but see they are unfortunately not available any more...?
