Build or buy , always hard to say.
Budget , can you do the fitting yourself ... time , the space. Space is important 'cause the bloody thing usually takes three times longer than you allowed for
Can you find something that suits your purpose and within budget is always a pain.
Throw pops or 3legs here a pm as they are the closest to you and have their ear to the ground to see what's out there.
