I think we also need to remember that with Weber, the volume they sell helps fund their massive marketing machine, I don't think the markup is quite as big as we sometimes think it is. Sometimes it's hard to look at two similar devices and see where the BoM of one is much higher than the other, you only have to look at Pro Q vs Weber to see this. I'm sure Weber's markup is bigger than Mac's BBQ but the materials and manufacturing quality in a WSM is a different class to that of a Frontier/E20. My only irk with Weber is their policy of recycling parts from products to use in others, while this is common practice in many industries to keep costs down, sometimes I think Weber attempt to fit a squarish peg into a roundish hole just to avoid manufacturing a smaller run of a bespoke part.
Anyway, back to topic. Looking at what you want and the price you saw on Fleabay, here's a suggestion for you
http://www.bbqworld.co.uk/bbqworld/prod ... name=16842I've seen these myself in Costco and they appear well built, Beefeater is a reputable brand with a history and given that it's not all stainless it looks like something that could be well built within the confines of it's list price. I assume it's last year's model hence the sizeable discount. Puts it in the same price bracket as the Fleabay model when you factor in free delivery too.
Also BBQ World are a brilliant company to buy from. My WSM's came from them and I had an out of round base on one. they had the replacement part to me within 24 hours.
