For clean beaches I took a punt on contis at 14.5 feet, a Sunset it was the top end though, and I am really pleased with it, the build is great, its light, steely and powerful, but slim. If their other rods have the same build quality then you could do much worse , Sunset is not a brand that is bandied about much, no idea why, I have no problems or worries with mine at all, love it !
I team it up with a Vercelli Spyra Nero Power, which it is very simiar to in action,they are both great clean beach rods.Both good for oht or otg, but will pendulumn if you feel the need .
For heavier stuff or bigger seas I go with my original Mk 1 AFAW Tourny Match, or Tourney Rock, both great rods for either mixed or rough ground.Both I backcast as they are both more pokey than the contis.
In your position, I would tend to go for second hand, keep your eyes open and scour the local fishing websites , something suitable will come up, as a beginner dont go for anything too stiff though, if you cant bend it you cant cast it, some anglers buy a rod, cant get on with it and shift it asap, you could get lucky quite quickly.
