Lot smaller than I thought (dont know where I got the idea from, but thought it was bigger).
Interesting.
Its not something I would consider right now, as I do have other things going on which I would prefer to spend the spondoolies on, but its obviously worth considering in time. It isnt so far as Im concerned something Id have because of freezing weather, but because it improves the ability of any system to clean and is more efficient time-wise.
Thanks.
