They work fine as starter kits... as another guy said, at some point you'll probably want to upgrade... but the old press would still be good to keep around for grunt work...
I started with a Lee Loader (yes, the old hammer / mallet required version), went to a Lee Challenger (single stage) press and Lee powder measure (all while I was a teenager living at home; my Stepdad got tired of hearing me beating on the Lee Loader all hours of the evening in the garage) .... moved out, and 12 years later I've gotten back into it (factory ammo was getting EXPENSIVE!!!), this time with decidedly nicer equipment of my own (Hornady LnL AP Progressive and one of their Classic single stage presses -- I guess I had to keep it all Red like the Lee stuff) ... and I do like it better than the old or current Lee stuff... but I have them (Lee) to thank for making it affordable for me to get into it all those years ago... So I say go for it, just know it can be an addiction, and you will find yourself perusing Midway USA catalogs all the time, and wondering about what rifle to buy to go with the set of dies you just bought 'cause they were on sale... Welcome to the Addiction (and you thought guns were an addiction).
Oh, and do check out some of the online shops... I like to buy a lot of stuff at Grafs.com ... 4.50 shipping on entire orders (except haz-mat type stuff)... and good prices. Might save you some dough.
