Welcome to

, Barly! Most of the Vintage Port produced in 2008 was Single Quinta Vintage Port; generally the second-label wines of the main Port shippers, produced from a single vineyard (quinta). These can often be excellent wines, and are usually a bit faster maturing which can be a bonus if you are thinking of drinking them in 16 or 19 years' time (which is usually at the lowest maturity point for Port), but they might not quite be as good as fully-fledged vintages, especially in the longer-term. Of those produced, Taylor's Quinta do Vargellas, or Quinta de Terra Feita and Fonseca's Guimaraens are all likely to be pretty solid examples of that style of wine from traditional shippers. Alternatively, if you want a full-blown Vintage Port, then something like the Quinta do Noval, Quinta do Vesuvio (both first-label Single Quinta Ports) or Niepoort Pisca could be possibilities, though someone who has tasted more of them is probably more likely to be able to help. Unless they are doing something different this year, it might also be worth noting that the Symingtons generally releases their SQVP when it's a bit older, so you might not see things like the 2008 Graham's Malvedos until 2020 or so.
Alternatively, you could look at 2007, which was a general declaration and may be a very good year in the end. 2007s to look out for, based on what I've tasted, are Quinta do Noval, Quinta do Vesuvio and Quevedo.
Prices are always a bit tricky; historically, in the UK, prices for older Ports have generally been quite reasonable (for an extreme example, I've just bought some 1991 Quinta do Roriz for less than half the price that Berry's is selling its 2007). But if you buy a case from a major shipper, through a reasonably priced merchant, you'll probably be doing fine. And, after-all, the Port is there to be drunk, not sold on.
