I was keen on a Centec 2A once. Then I saw one close up. There is practically no daylight between the spindle nose and the table unless you get one with a raising block. See picture above and mark where the tool tip will be without the raising block in place! And… wtf thought it was a good idea to have the knee lift round the back of the machine? I guess it was the past, they did things differently then.
Ended up with a TwinMill instead, simple, solid, but very basic also slightly short of toolspace, but not as short as the 2A. The worst issue is the table traverse is on the right side only, with the leadscrew not extending through the left side. This has complicated fitting a motor drive.
The smaller VBA Beaver Mill might be worth considering. Almost secured one once, but by the time I’d finished umming and ahing it had gone.
The Senior E type never appealed to me due to the ‘spaghetti’ width column, but perhaps E type owners with lived experience may wish to make a rebuttal!
