YES!!! Buy a table as soon as you can afford it. And definitely do not buy CHEAP!!! Read through the sticky topic in Tools of the Trade on tables. Look and see what everyone likes and dislikes about their table.
When I bought my table, I was really scraping by for school, and had not worked in 6 months due to a knee injury. I decided after talking to a few people that I knew I needed to buy my table and buy one that would last. There was no reason to buy a table that who knows what quality it was, and to say portable, but the only portability it was, being that it could fold up. In our business this is important because we never know where we are going to be. The lighter the table the better mid to low 20 lbs (anything more is way too heavy), and it must have a carrying case, not just the handles that are on the table.
I have an oakworks wellspring, which I absolutely love... I have no complaints, the only replacement for this table will be an electric table when I can afford it. Oakworks I read is coming out with an inexpensive table called "One" you may want to look into that if $$$ is really a problem. But one of my fellow students had the table from costco, and it lasted a whole 2 massages, and thankfully broke while she was working on her daughter. So it ended up costing her a lot more money to replace the table with a decent one.
