My advice would be, dont do it! If you can possibly afford it, save up for the 6910 - it cannot be compared with the cheaper Sunbeams in any way, shape or form. Better to get the grinder and a plunger for now, and start saving for the 6910!
With your tight budget, you might also want to consider the EM0450 grinder - same internals as the 0480 but housed in plastic and $30 or so cheaper.
If your budget is fixed, Id go for the Breville based on reputation.
