It also depends on the category of the product and what 'value' you hope to get from it. For example recently I purchased a Lego set, the biggest one I've ever purchased and it cost £565 (titanic) which is the most amount of money I've ever spent on what is essentially a display piece once built. However I enjoy the process of building Lego and this set is going to take me months to build, just devoting an hour or two a week to completing a section at a time. So the initial outlay is a lot but breaking it down to 1. the enjoyment of building the set 2. the enjoyment of displaying the set once it's complete as a sort of home decor item 3. the amount of time devoted to it (I reckon it'll take me about 35-40 hours to complete, but it'll be months before I see the end because it's just a lil hobby to do at the weekend) ...the cost almost doesn't matter.
