Looking for small corner computer desk

At home I had a small flat pack computer desk that I think I got
maybe 20 yrs ago at Big Lots Over the years parts have come
off including the brace connecting one of the side leggs and
the back corner. This morning somehow my hubby and my dog
collapsed the whole thing, My poor tension headache came back
in force!

Now I need to find a new corner desk, I really don t want to pay Ikea prices
Where would I look? Should I think about getting some help in building one?
I have a too small desk I can use for awhile,

Suggestions?
