I guess your main problem is having very wide feet might limit your options.
The army surplus Haix boots seem pretty wide and reasonable quality, not stiff enough for me, for about £50. You could have an awful lot of them for the price of the Meindls. I have a pair and use them for some stalking (very quiet) plus working around the garden etc.
I have a pair of the Meindls and while they are wide I didn't find them an especially good quality boot and the support was somewhat lacking in them compared to other options. I wouldn't buy them again. I have a pair of meindl mountaineering boots and they are very good quality but very, very stiff. Quite good on soft moor though.
I have a pair of Altberg Mallerstangs which are OK but not built to the same quality as the Scarpas I've had plus they wear pretty badly compared to the Scarpas. My Altbergs are pretty much done and they are only 4 years old (I have about 7 pairs of boots currently so haven't been wearing them constantly for 4 years) whereas I have Scarpa SLs here on my feet as a type and they must be at least 10 years old and have probably had 100 times the actual days of use of the Altbergs. Also the Altberg have a really bad design feature in the sense that the cross section of the little loops you lace through is rectangular and so they chew laces, when on the moor they can get through a pair of laces a day and that gets old real fast. They are comfortable enough and I certainly wouldn't rule them out but they have sufficient problems that I couldn't recommend them to someone else.
I have 2 pairs of Scarpa SLs that are still going, it is probably 10 years since Scarpa sold them, and they are the best general purpose boot I've had as they go stalking, fishing, walking etc. and I'm still wearing a pair as my "everyday" pair. However they've long since been discontinued and I really can't comment on their replacements though in all probability they are what I will try when I retire the Altbergs. My concern is that a lot of companies are adding "features" that cost nothing to implement and sell boots in magazine adverts but they are removing quality and it is possible Scarpa have done this as their new boots seem to have a lot of focus on "features" in the marketing.
So, it is very difficult to recommend something as in the end boots are quite a personal thing. As has already been suggested in this thread some of the less expensive or even surplus boots may well be worth considering as they seem to, basically, lack features but retain the same basic quality as big money boots and if you are only spending £50 you can afford to replace them every year even if they don't wear so well. In the end until you actually try something it is impossible to say how it will fit or suit you and that is always the problem with boots as you have to be doing a lot of walking to have made a reasonable comparison between different boots in a lifetime and, of course, by the time you get something good they've stopped making it anyhow.
