Mike, not sure of difference but just for light work (not fencing or roofing) so probably a finish nailer. I'll have a look at Parkside as I've bought a few bits of that brand. What model is it please?You haven't stated whether you want a frame nailer or finish nailer but I've got 2 air finish nailer, a Makita which is excellent and then I bought a Parkside nailer/stapler which is excellent value. If I had to decide now I've have settled for the Parkside which I bought new on eBay earlier this year. Lidl sometimes sell them. I used the Makita to nail down 12mm sarking on a 9m x 4m roof (fired a lot of nails) and it performed perfectly. I've only used the Parkside occasionally so far.
