I recently bought a jacket from Chequered Flag, they are currently selling a black Trialmaster style jacket on ebay at a very reasonable £89. Here's my quick review;

I wasn't sure what to expect for this price tag - But actually the jacket is really nice. It's a heavyweight 12 Oz wax cotton with a check lining that's exactly the same pattern as my Barbour International. The fit is good - not tailored but equally not too baggy. It has all the features you'd expect from a Belstaff Trialmaster, four main pockets, a zipped inside pocket, adjustable cuffs and buckle and strap at the neck plus shoulder and elbow patches. As for it's ability to keep the rain out, well I wore it on the bike through a 40 minute rain shower and it kept me dry !
What don't I like about it ? Well not much really, the press studs are shiny brass yet the buckles are antique, so it's a shame they didn't use antique all round. Also the press studs don't feel quite as good quality as my Barbour Intl, they spin around on the fabric rather than being stamped firmly on - that said they don't feel at all like they are likely to fall off. A nice detail is it also has two mesh vent studs under each arm.
Another feature is the interchangeable flag option on the left breast pocket - again a nod to Belstaff. Basically you get a selection of flags; Union jack, Stars & Stripes, Welsh, Scottish and Irish which use velcro to attach them to the tag under the pocket. But quite why anyone would want to fly the welsh flag is beyond me u k fl ag
The shoulder and elbow patches, well again being picky, but it would be nice if these were double stitched like a Belstaff rather than just single.
I've worn the jacket solidly over the past month and I have to say I'm loving it - It just feels solid. This jacket is the cheapest in the Speedwear range but I have say it certainly doesn't feel budget. They also sell a de-luxe 'Continental in Black or Brown (£169) and that has a zip-out liner and pockets for armour - So you can get some extra insulation and protection for a bit more cash.
