I tend to agree with the others comments. The Taig is just a bit too small. Not only is the work envelope limiting but the rigidity of the machine itself limits the cuts you can make. For the same ~$2500 you could get a manual dovetail mill/drill. Take a look at
Industrial Hobbies. I don't have nor have I ever used or even seen in person one of their mill/drills but their website sure makes a strong case for their mill/drill over the similar well known Rong-Fu and cheaper house brand imports like Enco, Grizzly, Turn-Pro, etc. For the same ~$2500 you are considereing spending on that Taig CNC mini-mill you can get the Industrial Hobbies basic manual SQUARE COLUMN mill/drill. It is a beast though compared to the Taig so you aren't going to be bringing it along to competition.
If you search around on their website there is a photo of a popular hobby type Seig X2 mini-mill (Harbor Freight, Homier, Grizzly, Micromark, etc.) sitting on the table INSIDE the Industrial Hobbies mill/drill. The Taig mini-lathe is about the same size as the Seig X2 mini-mills but the Taig is a little less "beefy" if you ask me. If you have the $ consider one of the Industrial Hobbies packages with DROs and power feed included with the mill/drill for about $3700. If you don't have the extra funds for the DROs and/or power feed up front you can always add them later for ~$1500.
So as others have said you are probably better off starting with a manual mill and required tooling first and then step up to CNC later if needed. Never underestimate the cost of tooling. You could easily spend another $2500 on tooling.
As luck would have it Industrial Hobbies has ready made CNC retrofit packages for their mill/drills for ~$4500 which includes software.
As I said I have absolutely no experiance with the Industrial Hobbies machines but I am strongly considering one for myself. I figure for ~$4000 I can get a really nice manual mill/drill with DROs and power feed delivered to my door. Once setup I can later add CNC for ~$4500 if I want and have a really nice setup for a total investment of ~$8500. I have the tooling covered since the Industrial Hobbies mill/drill has an R8 spindle as does my existing Seig X2 mini-mill.
If anyone has any hands on experiance with the Industrial Hobbies machines I would love to hear your opinions of the machine.
