I got the budget pine self assembly kit from Maisemore last year and it was fine. I painted the outside of the hive bodies as I wanted them to look white and pretty.
The only comment I can make is that some of the joints were a little bit tight and needed a little bit of tapping with a rubber mallet. Once together though they were fine. Im ordering another 6 brood bodies and 3 supers in February anyway, so they can't be bad!
Only problem I have found is that Maisemore dont supply Langstroth open mesh floors with the screen access from the back. I have to buy these from Thornes.
