Yeah loads of people hate cheap chinky stuff and rightly so, I'd never take a punt on a cheap turbo or laptop but I bought my depo as a cheap option until I'd saved enough to buy a toucan /syvecs (cheap gauge is better than no gauge)
3yrs ,12k miles ,2 engines and 1.5 bar later it still works ok and I've spent the defi money a few times over .
I found advance automotive very helpful when asking tech support questions about the £500+ pistons I'd bought off them but unfortunately most tuning companies haven't got the time to just be helpful and have got the "buy expensive buy once" mindset which doesn't suit me as my pockets ain't that deep
