I bought a TP Link Archer C9 for under £100 last year and it's been ace. Works happily with my OpenReach fibre modem, and Port forwarding works perfectly (I'm currently forwarding what is presented as port 80 externally to something in a much higher range internally)
I don't have a static IP, but use FreeDNS with an updater running on a Raspberry Pi updating it with my public facing IP every 10 minutes, so other than the occasional drop out, works really well. Currently using it for a RPi based security camera system
Note: If you do end up with an arch C9, there's an irritating bug that means you need to turn off the 'NAT boost' function for port forwarding to work properly. It's a good, solid, reliable router though.
