Last time I checked the HP8 SE with the Jensen caps was around £700 mark that's about double the cost of importing a Crack!
I have been blown away by how good the Crack pairs with the T1's
Have you taken a look at the NJC audio Monitor MK11? Its very highly thought of but not a common amp here, there is a review about on headfi. I have also seen comment on it being compared to a £1300 Bryston with very little noticeable difference.
That was actually the first amp I came across when I started to look for one a couple of days ago. I've decided I want a tube amp though. The "neutral & uncoloured" sound the company talk about doesn't seem like it's for me.
$400 with the Speedball Upgrade is definitely a good price (no idea how much shipping would be), but I would be too scared to even try to build it. I don't think I've even ever picked up a soldering iron in my life! On paper, it looks ideal but in reality it's not an option.
I actually posted in the FS that I was on the look out for a Bottlehead Crack or WA2, but I'm not holding my breath. Actually, I could probably find a Crack for sale but the WA2 would be the ideal.
