there are lots of options Bush
1st off - I would do some research rather than rush into a buy - I've seen lots of WTB threads from yourself in a short period of time
very impt to take ur time looking round these forums and deciding on spending ur cash on wot you definately want. Thats speaking from experience, I've made the mistakes, hope you dont repeat em!
bucket kit - have u decided which mandolorian u are goign for yet? boba? jango? custom?
you have a budget there - thats good! at that price range u would be looking at doing some work yourself. You'd be pushing to get a fibreglass at that price, esp.ly factoring in shippin to Turkey.
The Sarge has a re-plumb to whole house sale atm and is offering one of the best bang for buck lids there.
theres GB lids for abt $110 - but they ship from Canada; and my experience with Canada post to this side of the Atlantic has been.... a bit hit and miss.
cheaper options - scracth build with WOF plans, modify a DOn Post, Bradley Fett ABS lid.
there are also a few UK options which may be cheaper to post to you.
