Have you checked out Jackson and Gam? I'm guessing you're in the UK and I don't know how popular those are out there, but from the price points I've seen, you're going to get more for your buck than with Graf. They seem to be slightly less expensive. For example, I'm in Jackson Elite boots, I think one below the most strong, and paid about $485. My Gam's were about the same stiffness and I think were around $400. In comparison, I think the Risports I had, which were less stiff, were about a hundred dollars more. When I bought my Jackson boots, I made sure to keep price as an important selection criteria. If the fit of a more expensive brand is absolutely necessary, go for it, but it's also important to be conscious of the price and what you need, etc.
As for blades, the MK IV blade you mentioned is not bad per se - I skated in it for quite a bit. But if you bump up the price a little bit, Ultima has a lot of options that are better and will cost less than the more 'traditional' brands. I have the legacy I think? I compared the price to other blades that were similar and the price couldn't be beat. They're really smooth, too. Eclipse has a similar price point if Ultima isn't for you. This is based on NA prices, though, and being in the UK means that Wilson and MK might be pretty reasonably priced for you.
I swear I'm not a Jackson sales rep! Just a happy customer
Hope this helps!
