disco vs 90

Hi, what would you do? Have you ever owned both? Just sold my 90 county td, but what next? My needs = Muddy dog, muddy boots, horse feeds, no water in my field so water containers (but will need to pull a water bowser soon) across a v v muddy field, roll and harrow my field, Me + one most of the time (&dog), but it's also my daily driver so maybe a bit of luxury & cleanliness would be nice for a change. Can a disco be as practical as a defender without wrecking it? Was pretty much decided on a disco at least for now, i dont want to spend a great deal as the remainder is earmarked for a horsebox, but then saw a L reg 200 quite cheap, it's a hard top though which i didn't really want but should i compromise?But why is it so cheap! The disco insurance is about £100+ more than a 90 but about £2000 cheaper (apart from the one i've just seen) to buy than a 200 90!(never buy a td again) If it wasn't for the horsebox money i would be looking at aound £5000 for a nice 90 county but was going to compremise at about £2-2500 for an m reg ish disco. What to do, what to do??!?!? Please help!
(sorry if you've already seen this, i put it in 3 catagories for max feedback!)

The disco would be fine its a very capable offroader, for driving across a field and towing a bowser it will be fine, take into consideration how much the horse has destoryed the field, if the field is very muddy tyre choice will be important.

the only diferences between a disco and a defender is 10 inches and the price, they both have the same engine/gearbox, and axles and diffs, its all down to choice, basically an r reg disco will cost you 4 grand whereas an r reg defender will be closer to 7 grand, you do the maths

The only differneces are turning circle, comfort level and cost! The Disco will do anything that a 90 will.
