All in Ones, which require the least mods?

[ColinD]

Looking at setting up an AIO Nano, debating on purchasing a packaged unit or gong with a DIY. Price wise I seem to be coming out at about the same once I take into consideration everything I need for a DIY. Which units require the least amount of Mods after purchase? Really liking the look of the Cadlight 22g, any opinions and what are folks shipping experiences with a tank this size?

Thanks
Colin
