Mate, I bought my first reel for about £60 off circuit hydraulics I bought my second for £10 off eBay. I bought my third for £20 off eBay. Bought 2 spare handles off circuit hydraulics for £12 each. 
I also picked my trolley system up off ebay for £80 with charger 
You just got to shop about, as it pays to shop. There is plenty of used hose and reels going for about £30-£40 on eBay, and most can be posted just sort it with the seller. 
There was a full system on eBay up north east for £200, I would of bought if I could of got it shipped.
