Try Novastar, might be a bit more than 2k (but not much more!).
Depends on how basic you want to go.

I actually bought a Novastar for my prototyping work. I looked hard and long before pulling the trigger. Most ovens appear to be IR-based, which means that they have very little thermal mass, no convection heating and no circulation fan. This causes trouble with uneven heating, burnt connectors and all the other very known issues. All Chinese reflow ovens appear to be IR based.
Specifically, I have the below GF-C2-HT hotplate-based reflow oven. It took me a while to figure out how to achieve the proper reflow temperature curve since the heaters heat the hot plate and, subsequently, the thing takes a good 30 minutes to heat up! The trick is to fully heat the oven to some 300 degrees C and then put in the board with stand-offs such that it doesn't sit directly on the hot plate. With the circulation fans going, the board will be evenly heated on both sides, the correct temperature curve will be achieved and boards will be reflowed in about 5-6 minutes.
Note that pre-heating the oven to 300 deg C allows the target temperature to be reached in about 5 minutes. If only heated to 250 degs C, the ramp-up takes too long and the whole reflow temperature curve will be drawn out in time.

However, I have temperature profiled the above method and it is good enough for prototype board assembly. The temperature curve is not exactly like the ramped reflow curve, more like a "capacitor charging curve". I looked at the time spent in each zone (pre-heat, soak, reflow) and my oven is fairly accurate. I think the GF-C2-HT is over $4K but I found mine for $2K new on Ebay so overall a good compromise. In addition, I now have a large hot-plate, which can be useful.
