smiths posted some useful info about agencies (IMO) https://www.ukpunting.com/index.php?topic=62880.0
There no correlation, between price and quality, when it comes to W/G (IMO). I've punted a few (W/G) priced @ £180+ PH that were far worse than some £60 P/H in terms of service and attitude. Beauty is very subjective and ranks lower than service and attitude when I punt. So, its down to what a punter considers true VFM.
