First, the standard suggestion we make for beginners here - tell us a bit more about your intentions. "3-season" means different things in different parts of the country. So, are you in New England, the Deep South, Texas, Great Lakes area, Pacific NW, Great Basin (UT, NV, AZ), Rockies (CO, NM, WY), California? (Hey Dave, you should put up a questionairre for beginners to check the answers to help us answer these standard questions).
Second, how far do you intend to backpack in the next couple of years - 5 miles or less to the campsite for a weekend, 5-10 miles, multi-day up to 20 miles total, add distance as fast as you can get your legs under you? This, of course, depends on how good health you are in and how old you are.
Third, will you be camping out in rain, pushing the 3rd season into the early or late part of snow season, or other adverse weather during the next couple of years, or will you leave the less pleasant weather to the future after you get a bit more experience?
Fourth, what's a "lot of money" for you? Are you a student with your total income coming from evenings working at a fast food place, a starving college student (or, even poorer, a starving grad student), got a good job so plenty of money as long as it buys quality, or what (general category, so we can get an idea how cheap or expensive to go)? Keep in mind here that the general rule in outdoor gear is that quality costs money. "Quality" includes not only the stitching, but also how well the manufacturer stands behind the product, how heavy the bag is, how long it will last, and so on. For example, a Primaloft mummy bag for temperatures above 15F from Marmot, Integral Designs, North Face, Sierra Designs, or other quality manufacturers will last 5-10 years of frequent camping, and runs currently in the neighborhood of $100-200. Does this sound like an ok range, or is it "a lot of money" for you?
