hi ive got one of these and was looking everywhere for one, i was lucky when i purchased mine I was able to look at one before purchase at lakeside, the staff were very friendly and helpful
after trawling the internets for an age i returned to waterstones at lakeside again the staff were very helful and allowed me to measure up my machine to the others they sold, i found it was approx the same dimensions as the sony prs600. i went to the sony shop in lakeside and tried it for size – perfect but being the sony shop they had very little stock and were way over priced (£50 for a standard case without a light).
in the end i came home and ordered this one
its a bit pricey after postage to the uk but will do the job, ive also ordered thier light that runs of aaa cell and fits neatly into the case.
hope thats helpful
