so, i have been looking at K3/4/5, as they are usually between 2-3K, or an SRAD which is less, but i don't want to buy a total rust bucked or something that will need lots of work like my FZS600 did i.e. shocks and springs, so at 18 stone i wonder how well its setup for my big bones

You need to consider any bike you look at at this age may require a new shock etc so providing its in fair condition it may be worth going with an earlier bike and spending some of the money you save on the asking price on suspension.
