Thanks all. Yes I've seen a few bibs in Aldi recently, but my size had all gone. Will watch out for further items.
As far as bibs go I really would by the best you can, not because of some snobbery but because it really does make a difference.
If going DHB, get the high end ones, they are great. For the summer I bought some Morvelo bib shorts and they really are the best money I have spent on any garment. The comfort and quality in material really does show and makes cycling distances a pleasure comfort wise.
I have cheap and reasonably expensive tops but I don't really see any real reason on spending more on tops providing the fit is good.
