Ben,
If cost is your only criteria for buying a skimmer, than yes this is the best option. However, IMHO, this should not be the only factor weighing your decision.
The questions that I used for buying my skimmer were, "what exactly do you want the skimmer to accomplish" AND "what type of tank are you going to have (FO, Reef, etc..) and will this skimmer support this type of tank."
Hopefully, these questions will give you a better perspective in your decision making. I was torn between the BM 250 and the H&S 250. I finally settled on H&S with the reason we talked about last week.
HTH,
Kirk
