Ive used them before for a trial period, it was a pretty good service. however, I found that unless you can get through 3-4 games per month (rather than the 1-2 I get through) it works out cheaper to pre-order games (to get the cheapest on release) and when finished with them sell them on here on ebay and the small loss you incurr is likely going to be less than the monthly fee from boomerang!
