pentax produces good DSLRs for the price you can afford. also, if you are not a pro photographer and just started photography, get started with one of the megazoom cameras (also called bridge cameras), they have almost all features DSLRs have, some even have features that DSLRs don't have but the thing is they are not fully developed as in DSLR, e.g. a DSLR might offer shutter lag shooting upto 5 minutes, but a megazoom might offer only up to 1 minute. 
canon is good for point n shoot, but that's not true regarding megazooms, look into panasonic, they are highest rated megazooms. fat beast or drkanchoo owns a megazoom, check somewhere up in the thread and ask them before buying a camera.
but, if you really want a DSLR for about 700, i'd say go for pentax, they are good camera makers.
