I think most here would recommend anything by Knipex (aligator/cobra & wrench pliers) and Bahco (adjustable pliers) to start but I doubt you'll find them discounted anywhere. Most of the major branded cordless kit is good enough, Makita, Dewalt, Bosch, Milwaukee etc having well established platforms and that really comes down to personal preference. For small diameter masonary I know plenty of tradesman that prefer percussion over SDS but once you get over 10mm SDS is required say for a 22mm pipe run so you may prefer a mains powered SDS for that and possibly core drilling work. Keep an eye out from usual tool retailers for sales of combi kits to get a start and once you have a platform you can add bare tools reasonably cheaply as well as add higher capacity batteries.
