I agree with the above. The kind of pump depends on your BFing goals--ie how much milk you need to give via bottles. Also women respond differently to pumps.
Given the difficulties you had the first 2 times it's great you're trying again. A lot of people wouldn't. It'll be good to know what to expect, to know how BFing (esp in the beginning) is different from FFing so you're prepared. Esp since you'll be caring for 2 other LOs. It's good you're here looking for info. Might also check out kellymom.com.
Pumping for one or two bottles is different than pumping for a half day of food. If you're doing the latter you're probably better off renting or investing in a good pump.
Good BFing and pumping inside the first 12 weeks is what tells your body to make enough milk. If you're able to just BF for a while, it's goes well (wet/poopy dipes, weight gain) and you establish a good supply, you might do with a cheaper pump.
If you need/want to pump while your supply is still being established it makes sense to rent a hospital-grade or at least a high quality retail. It's tougher to increase supply after the first 12 weeks.
