Well, that being the case, set your price and get the most bang for your buck. T3i would definitely meet your needs. The only cons of going with an entry level rather than a "prosumer" model is that you usually have to do more menu-hunting to get them to do things, whereas the more "advanced" cameras usually have dedicated buttons. For example, let's say you're shooting in manual mode. Any vintage film camera has a dedicated aperture control and a dedicated shutter speed control. Set your aperture, set your shutter speed, and you're off. A Rebel series DSLR, such as the T3i, will have one control wheel, so you'll be able to set the shutter speed, but then you have to press and hold down another button while using the same wheel to set aperture. My 40D (and other x0D cameras) have two control wheels, more like a film camera (they have other advantages, obviously, but if you're doing long exposures on a tripod, they shouldn't matter too much to you). If you can live with that, though, you should certainly be happy with it.
