My Skyline Ranch playpen is back in stock at Zooplus if anyone is interested. IUnfortunately the price has gone up a lot (like with most hamster things). I'm sure I paid £25 for mine originally! It's now £44.99. But still £5 cheaper than the Happy Henry version (which is very similar and the same size).
