You will still need to get your own bee suit (second hand ones usually have a hole somewhere...), but you could join you local club as Jaykay says, and then maybe volunteer as a helper to one of the older beekeepers. They quite often like to have someone to help, especially if you are able to lift heavy supers for them.... Lots to learn that way and a few jars of honey probably as well...
I would stay away from second hand equipment, unless you a) know where it is from, and b) have a blowtorch/steam steriliser set up to clean the hives. Always get your own new frames/foundation for the supers and try and change the brood frames asap for new ones. Best would be to start off with a nuc and build up your own colony that way. Too many diseases around just now, and also unscrupulous businesses selling bees (often imported queens and totaly useless in the british climate!) Buy local is really important for bees.
