Given that this is your 1st DSLR you're probably excited so my advice is probably the last you'll want to take. But of course, that doesn't stop any of us here from offering it anyway!
Since it is your 1st DSLR, you've got a LOT to learn. If you just wanted to shoot JPEGs forever, you probably wouldn't be taking the time to come here & read all the rumors, input, ideas, etc. Clearly you're up for taking your photography to a higher level. And since you've got a lot thats new to you, my advice is: Don't invest too much your 1st time out.
The 700 or the SL1 (or the 60D) will set you back a good bit simply because they're new. And in a year or 2 when you resell, you'll lose a good bit of value regardless. Think about picking up an older model that may not have all the new bells & whistles but still takes an excellent photo. For example, since you seem interested in the rebel line, a T2i. It takes a very good photo & shoots in full Raw/manual/etc. You can learn everything you need on this camera and still take excellent photos while you're learning. AND you can learn what you want or need in your next camera so you can make a more informed (about your needs & wants) w/ your next purchase. Also, in the year or so you're using it, the SL1,700D & perhaps the 70D will all drop in price. Probably significantly. If you still want them, although I seriously doubt you'll want a SL1 or 700D at that point, you can save a few bucs.
If you decide to buy a T2i, or perhaps a T3i or you really want a flex screen, I recommend going thru Canon direct and picking up a refurbished one. They go on sale fairly often so wait for a 20-30% off sale. There is a sale going on now but the T2i sold out very quickly. There is a reason for that. Fyi, it was $335 US for the kit. If you don't need the lens for some reason, you can sell it on Amazon & clear about $100-150 dropping the price of the camera to about $200. Its a fantastic deal so you can use the money you save to pick up a halfway decent lens & some software (LR4 maybe?). As an fyi, I use a T2i as my P&S/biz travel camera. Just bought it 5-6 months ago. I love shooting with it & the photos are every bit as good as what comes out of the new rebels.
Regardless of what you decide though, happy shooting & welcome to the DSLR crowd/addiction group!
PS: if you have an old canon p&s that you don't want & can't sell, Canon has a loyalty program that gets you a signficant discount on refurbished DSLR's if you trade in the P&S. They technically want broken ones so if it doesn't work, so much the better. Call Canon USA direct, ask about the program & they'll give you prices on their current stock so you have an idea what can pick up. Take care! Sk
