Purchased a couple of weeks ago an SLX 35, have used it once and it's fine, wish now though in hindsight that I'd just stumped up the extra cash and bought the extreme....can someone reassure me that they aren't TOO dissimilar... 
SLX 35 very whippy over 25 foot
Yeah, the only job I did was a townhouse style hotel where it was on full extension, can't say it was the best experience I've had so far, maybe I'll sell it after one use and lose £100 on it 
Honestly you won't lose that much.
Stick it on eBay, ending the auction on a Sunday evening. And you will mayb lose £50.
Gardiners poles sells like wild fire on eBay.
