Exactly!!!
The point I was trying to make is that the enclosures look and husbandry effectiveness are not necessarily in proportion to the money spent on it.
I saw many great looking enclosures on my recent visit to Scotland at the Highland Wildlife Park, basically they were fenced in patches of wilderness with added animal houses. Very, very good and at relatively low costs. The Lemur walk-through enclosure at Blair Drummond was similarly cheap, effective and great looking. I'd also point out the enclosures at the fledgling Yorkshire Wildlife Park which are all very well done and would not seem to have cost a fortune.
Additionally, throughout many UK zoos there are some good looking, inexpensive, enclosures for many a variety of small mammals.
Yes, on examination you realise the enclosures wouldn't have cost astronomical amounts but the enclosures visual impact is not compromised as a result of this.
I will concede however that it's probably difficult to do excellent pinniped enclosures on a shoestring budget (which may explain why a number of medium, and larger collections avoid these species or are seemingly going out of them).
