What are 'normal' fees for a regular (just to check if everything is ok) visit to a pediatrician? Am wondering if $250 is too steep and if I should consider another more affordable PD.

If your $250 is only for consultation, it is very expensive. If the cost include medicines and tests, it is not expensive. Normally PD charge consultation between $80 to $100 per visit exclude medication. For first time visit, the fees will be more expensive, which range from $100 to $150 for consultation. Subsequent visits will be cheaper.
