Plusnet using my own router here also - no problems just use PPPOE with the supplied username and password.
If you go this route I suggest accepting the free Plusnet router as if there was ever a problem with the "line" Plusnet check you are connecting with their router (or they at least used to in my experience - many many years ago since I last had to do this though). I assume this is to just make things consistent for them whilst diagnosing faults.
You just have to remember to NOT throw away the router as they have started to ask for them back. Just stick a post-it on the packaging to remind you before throwing it in your wardrobe for safe keeping.
If you just want a simple FTTP connection say at 150/30 speed you should be paying around £20/month at Plusnet for a new customer on a 2 year contract. At time of writing equivalent to £20.33/month according to MoneySavingExpert.
Just remember Plusnet do NOT offer landline / voice calls.
[Edit: Just clarified that you probably need to be a new customer to get that excellent price at Plusnet]
