Tractorhouse.com will be a good place to search for your tractor. Deere 2140, 2150, 2155 would be affordable models that would fit what you are looking for. A 3010 or 3020 would be bigger than that but would also probably be easier to find.
What are you planning to plant? Reason I ask is just making sure you truly want a drill instead of a planter. Planter will be able to plant corn, soybeans, sorghum for you where a drill will be better for small grains. If you google 2 row food plot planter there are a few places out there that cut down larger planters and refurbish them for food plot use.
