For that sort of money, you can just about get an SG2100 motor (maybe £75), and a Triax TD88cm dish (around £45). Not Goonhilly, but a very reasonable starter setup. Will work with your SS2 as well. You might bust your budget if you then have to fork out on an LNB (£10-£25) and some wall mounts (£? - can always make your own!). Don't cut corners on the coax either, buy the best you can afford, within reason.
