Could you tell me if it is correct and natural to say my tablet is an average price meaning when it comes to price, it's average? For example:
Even though my tablet is an average price, it fulfills my needs.
If it's not natural, would it be more correct to say my tablet is average in price?
"My tablet is an average price" is understandable, but sounds a little stilted and non-fluent, partly because it sounds like you're saying your tablet is a price, rather than having one. Also, average is a little unusual in this context.
It would be more idiomatic and fluent to say
Even though my tablet is only a mid-priced one
(Examples of "is a mid-priced X" usage.)
or maybe
Even though my tablet is of modest price
(example)
or
Even though my tablet is of moderate price
(example)
