Hi Phil,
there are obviously many outlets for this cable, but I tend to use a few such as Comtec direct, Mayflex, Mills ltd, Minitran, as they all do next day delivery.
good idea to future proof the property, as you tend to do cabling as few times as possible....I'm reading 25 years plus above!....so go ahead with your plan...the secret is now to over engineer the job as this would just be a waste and not give 'value engineering '. Which is a term that seems to be I merging in the industry.
cat5 e shielded would be fine for your home network if 1 gig is all that the manufacture's of PC's and gaming devices are planning on giving us for the foreseeable future, but I suspect within five years we will see 10 gig gaming machines for home network use. and possibly 10 gig NIC ' s. ( network interface cards).
The shielded modules and patching panels are easy to terminate and the sales teams are usually please to get you on a free training day for their products.
good luck with it!
