I saw those too, didn't realise they were air shocks! I had some on mine before, then went over to koni's after getting some advice on here. The thing with air shocks is they make the whole of the suspension rely on the shock towers, which aren't designed to deal with that level of stress and could lead to the towers failing.
I searched on ebay a few months ago for 2nd gen shocks, they were coming up from places like John Wolfe and US automotive for about £35 - £45 each. There are a pair of normal Monroe gas shocks for £80 delivered from Ultimate Spares of America

Same model for the fronts £70 delivered:

Monroe make OE spec shocks but unfortunately as all of the above listed companies do, they buy the economy (cheapest option) and sell them at normal prices. So combined, it would be £140 for the full set of 4 economy shocks delivered.
Alternatively, Rockauto do the OE spec (daily driver, not economy) Monroe shocks for £17 each, so a set of 4 including delivery to the UK is £115. So £25 less and better quality.
I would (and will) go for the rockauto option and then add in some service parts to make the most of shipping, like oil filters (£2 vs. £10), gaskets, spark plugs (£8 vs. £30) thermostats etc.
