Shocking shock prices??

Although my T2 passed its MOT this week :smile: front end is decidely 'floaty' I'm guessing all the shocks are original at 113k miles so probably well past their best, have seen Monroe Gas shocks on ebay which is a name I know and trust at £75 front pair and £85 rear pair,with 2 year warranty. Having found out today when the log book came back that it has been written off previously ops: ( theres always a reason for a car being cheap!) Dont want to spend too much money on it but potentially falling off the road with 1600kg of caravan on the back doesnt appeal either!
How does that sound price wise? any other recommendations on manufacturer/suppliers at decent prices... not intending any 'serious' off road use just a little light green laning and lugging kids and caravan and all the other junk we have to take with us!

Thanks in anticipation of your worldly wisdom....
