Alright guys. I'm after an 80mm refractor second hand and considering the Skywatcher ED80 DS Pro or the Explore Scientific ED80. I know the Explore Scientific is a triplet over the SW doublet. Are there any others upto £450 second hand that may be better? I'll be using it for visual and using a DSLR. Cheers.

I will hopefully be in the same position in about a months time, so will watch this with interest,

As I have one, and as others that come along will tell you, you get a lot of bang for your pound, so I'd recommend the ED80, especially when coupled with its matched reducer (recommended for photography)...

......move over a bit?

When my turn comes, and since reading the book! I have considered getting an ED80 (bigger maybe) for quick visuals and to progress into a little astro work.

I bought a Stellarvue 80mm APO triplet (f/6) several months ago to compliment my CPC 11" and could not be happier.  However, I have not tried the others for comparison purposes.  Getting an 80mm and adding a focal reducer (I use a MallinCam MFR-5 II focal reducer, 0.33x to achieve f/3.6) gives you two terrific FoV.  Finding a good one second hand one might be a challenge but it will be worth the wait.

I think my 80mm F/6 APM triplet has the same optics, and I like it a lot. It is faster than the SW ED80 (which is a cracking scope by many accounts), and with a reducer (I use the Tele-Vue TRF2008 0.8x) you reach a very useful F/4.8.

I love my Skywatcher ED80 ds. If I could only keep 1 of my 3 the 80 would be it. Put the 0.8x lightwave reducer on the back of it and it's a cracker, what's more it's light enough to do quick setups.

Grabbed this image of the Veil nebula doing a camera test last month, the fates willing I hope to get some proper data this weekend and do it justice

The TS 80mm f/6 gets good reviws but you'd need to be looking s/h.

Buying new in your budget it's hard to beat the Skywatcher ED80.

By SW ED80 I meant the Evostar  (80 mm F/7.5)

The Explore Scientific and StellarVue 80mm F/6 both seem to have the same optics as the APM I have (it's not the LZOS version). TS also has a similar one

There's also the Skywatcher Equinox 80ED, same optics as its cheaper brother, but faster (F6.25), and sturdier tube.

Am I right in thinking that it being faster allows light to be gathered quicker therefore shorter exposures required?

correct- but other factors can affect your exposure time as well (e.g., camera, light pollution, etc)
