Ours is the Seagull IV X-1F, average capacity is 1000 gallons. Bought it from the London Boat show a couple of years ago so do not know which would be best source now. Initial outlay was around £150 to £200, sorry cannot be more precise. That inlcudes the separate fawcet and all fittings. Replacement filter from ebay, under £60. Hope this helps
The cheapest ones I have seen so far are 340 pounds!
