Yeah, Koskinen is VERY common in Finland so i assumed you were from there
My husband is a motorcycle racer (Sears Point, Laguna Seca, Willow Springs, etc.), and I've learned from him that when watching races (nascar, olympics, etc) to look out for last names that end with "inen" More often than not, they're finnish!
I really like
www.rochenhost.com/
for speed, reliability and support. Not the best in terms of space and bandwidth but otherwise, they're great. For better bandwidth limits, check out siteground. They are pretty knowledgeable about joomla so joomla specific questions are never foreign to them.
rochen are decent but very much a pain in the arse - they will close your account without any warning if you have not updated a component or if you're using too much cpu (not just about bandwidth) - understandable but rather than communicate to a better solution - they literally just close your account and you cant get access to anything without wasting hours - so if you do use rochen and you're not 100% - keep regular backups - because if they do close your account then you'll want to get it live somewhere else as quickly as possible
saying that - if you keep your account 100% up to date - rochen are fine and you'll be happy with them
