Rich, when you price the cylinders, TnT takes two large bore cylinders, a high quality valve, and a ton of hoses and even more fittings, it will all add up. I put TnT with a good quality 3 spool valve and 3 remotes to the rear all with quick couplers (6 in total) and the attachment on Kubota to add the power beyond not to mention the hardware to mount the valves I spent about $1300. Here is a picture of my setup. As much as it costs, having that adjustable top link is invaluable, worth its weight in gold. I need the 3rd spool for my hydraulic rippers on my boxscraper and a Harley rake, if you ever plan on adding a implement that takes hydraulics, add a 3rd spool. Rat...
P.S. your price is not that shocking as TnT and adding spools has been discussed many, many times here at TBN.
