I know it’s not your answer but they aren’t too expensive anymore, I got one from a man up in Antrim, Richard hill 00 44 7745 868776 very good to deal with
If you're in the Munster area Darrenskayaks.com is in Durrus and does half day fishing trips and has just imported a budget range. Full disclosure he's a sponsor of http://www.Irishkayakangling.com my club. Register on the forum and have a nose around, we also have an All Ireland championship with Castletownbere Saturday week followed by Cahore, Culdaff, Ballinskelligs, Ardglass and Muckno so call to your local one if you want to see what its all about.
