Hi Mitch, Welcome... The full hive is a more expensive than a traditional hive, but you need to look at what you get. The hive is complete, comes with all the right angles (brood slopes forward, Flow slopes backward), screened bottom board, western red cedar, the Flow super is specifically designed for the Flow frames to fit perfectly and comes with observation windows. If you were to buy a similar hive setup such as a Warre' (much smaller) it wouldn't cost much less. You don't need to buy the full Flow hive, just buy the frames and adapt a standard 8 or 10 frame box. Many of us have done and it works equally well. And on to the extraction, have you priced how much it costs to set it all up including a bee proof and food safe room? You are looking at some serious cash outlay. I know I have done it. Decapping knife and accessories ($200), tubs for separating wax and honey ($100), comb scratcher ($20), Extractor ($1500), re-fit of the garage with shelving, new paint and bee proofing door seals and windows ($400), Wax Melter and honey buckets ($150)... it adds up.
At best you only need a hive stand ($0 for a used pallet), hive tool ($20), smoker ($70), veil ($20), jars or a small bucket, a few sheets of wax foundation and bees. I think you get my drift.
Oh and don't forget the pancakes! ..
