suggestions?
Go to a proper climbing shop, try on every single harness, they should have a rig for you to try sitting in the harness, do this with each harness you try on.
Choose the one thats most comfortable and fits within your budget.
Other things worth considering are....
number of gear loops (if you're tradding, the more the better, if only sport you don't need so many)
positioning of gear loops (comes down to personal preference, but ask for some gear to clip on and play around with)
adjustable leg-loops (handy if climbing in winter when wearing extra layers on legs)
Only you can assess these though.
