You can have cheap and fast, but not BIG. Or you can have Big and Fast, not cheap! Or, you can have Big and Cheap, not fast! In your case, you have cheap, and fast, not big!
You cannot have it all, The stool legs have to be level!
You mos' def' won't get XP updates! I would go the 7 route! At least it won't be a bot!
