Hello there!
Just thought I'd let others know about this - basically I needed a replacement neck for my Sire P5R and got in touch with Thomann.de They told me they can order one and would cost me £40 plus £10 shipping. I was a bit cynical as it sounded far too cheap but long story short I got it today and it's the real deal, Rosewood fingerboard and all. Only things not included are the tuners, string tree and back bracket but apart from that it's good to go and an absolute bargain so I thought I'd share the info! Only downside is the waiting times from the Sire factory, mine took about a month and a half but hey it's a minor inconvenience all things considered.
