This subject is worth doing a bit of research before spending your hard earned pennys, we have been looking at them for a while now, would appear that most of the units you buy for less than a hundred quid generally fail quite quickly for various reasons, what we have decided is that rather than keep wasting £70 here and £80 there we would buy a semi pro one, the extra £100 initial outlay would soon be recouped in less spoiling of produce etc.
What i would reccomend is you take a minute to look at the cabellas site, each is reviewed indipendantly by customers, we are sending for the one that is about £200, we have bought from cabellas on several occasions, their shipping is very efficient and prompt. We have no connection with them other than being thoroughly satisfied customers.
