Just a suggestion, 2k is roughly the deposit required to get started on a premium 16-20 mirror via say Suchting, Zambuto, Lockwood ect. The lead time is roughly a year so you have that long to save the rest, that way you end up with top quality, rest of your life mirror.
Then while you are waiting you can decide on a kit eg telekit, dobstuff or if you have access to a premium dob, a bit of reverse engineering.
Another option, SDM need a roughly a 50 percent deposit to get started and the lead time is about a year. Spread the cost over a couple of years and you can end up with a top shelf scope that will need no futher modification.
Invest in quality and a few years down the track you'll be glad you did the hard yards now
