oil pressure switch???

I've got an oil leak coming from my oil pressure switch/sender unit. It seems straightforward to replace, but I thought I should ask: is this something I should attempt myself or something I should leave to a pro? It's a 1994 with the 2.2L 4 cylinder.

I have a '96 and I replaced mine in ten minutes. The only thing you will need is a deep well socket so you can get over top of the connector without breaking it - care is needed. If you get someone to do it, they will probably charge you around $150. Also, save the old one in case you can't get the new one in.
