CORTECO hub seals?

My wife is in the UK visiting family and I thought I'd have her bring a few bits. One thing I need are RTC3511 hub seals to fit my D90 and D1's (I know the D1 specs a different seal). Are CORTECO about the best for the price (which seems about 2x Allmakes price)?
Who has the best price on them?

Also, do they make a quality hub seal for Series IIa and ('79 and earlier) Series III Rover axles? If so, anyone know the PN?

Ah asked about these a whiles ago as ah got some in a job lot o' stuff ah bought, and as far as ah could tell they were quite good. Stuck them in mine and all has been well so far after a year or two... far better than the ****part ones that lasted a few months!!

Dunno if ye could try doin' a search with yer axle numbers or summit, might be worth a try... and if ye find summit, get it sent to where yer mrs is goin' tae be

Right, I've been using them for a few years, but I'm out and need to get some more, was just wondering if I should stick with them, or was there a better (or just as good for less) brand.

Well, I need to order these Monday or Tuesday, and now can't remember who I got them from before.
Anyone have lead on who has the best price on the Corteco brand hub seal?
