To PDF or not PDF - that is the question

I have been looking forward to the release of Augustus to Aurelian, a rule set covering the Principate Roman period or Early/Mid Imperial Rome -  when the legion ruled (sounds like a good name for a set of rules, but I digress). I like period specific ancient rules and, as I have plenty of appropriate figures wanted to give them a try out. However my heart sank when I realised that it would only be available as a PDF.

I suppose that I am old fashioned, but I so much prefer a bound book.  I have previously bought a couple of PDFs in the £5 - £6 range but the asking price for this is £12.

I would have quite happily paid £15 - £20 for a bound copy and if it had been priced at £25 -£30 would probably have bought it with a sigh.

Having posted to this effect in a couple of places most of the feedback is that £12 is not unreasonable.  When you think of all the effort that will have gone into writing, playtesting and producing these rules of course £12 is very fair.  It just that to me paying twice that amount for something I can hold in my hand as a printed version seems fairer.

I would be very interested in others comments on this topic
