Hi,
The model is SP500, its about 3 years old, its VERY clean and VERY tidy. Sorry but I can't get a photo online just at the moment, but paste the following link for all the prochem spec. - hope this helps:
prochem.co.uk/polaris.htm
Regarding the price, I am not at all desperate to sell, so i think that I will just consider any reasonable offers that are made rather than state a price at this point. The next logical step would be to list it on Ebay, prob in about 6 months time, which is usually how long it takes me to get around to these things. - SERIOUSLY, its taken me over a year to get around to posting it on here!
Cheers
