I have an old Viking that came with a small table when it was new. Well, I inherited it so I just got the machine and the case. I tried FOREVER to win the table on ebay (for a couple of months) and never could. I would see these tables sometimes go for upwards of $60! And they were like 30+ years old and not in the greatest condition. So my husband ended up making me one out out of laminated wood and it has made sewing large items such a dream.
I also bought the acrylic one from AllBrands for my newer Janome and it was money well spent. The tables take the weight of the quilt so you are not constantly adjusting it so much.
