Where do you want to go in Holland?
If you're just looking for any ol' EH airfield to have in your logbook, EHMZ is probably the closest to the UK and rather cheap.
If you want to visit Amsterdam, the easiest/cheapest is probably EHLE. EHHV is physically closer to Amsterdam and slightly cheaper but it's got arguably more difficult circuit procedures, is harder to find and is rather short-ish grass with trees at all ends. Plus the public transport journey from EHHV to Amsterdam is more complicated and only marginally shorter than from EHLE.
If you want to visit Rotterdam in a light single, the Vliegclub Rotterdam occasionally does handling too for visiting pilots. That should bring the total cost down from 200 euros to maybe 45 euro or so. (20 landing, 25 handling)
On the other hand - don't rule out Schiphol straight away. Yes, you won't be left with much change of 300 euros after all the bills have been paid, but you get the unique experience of landing at the third (?) largest airport in Europe. You will most likely land at 04/22, so you're normally not physically mixing with the big iron, but the tower frequency for 04/22 also handles most of the other runways. Of which at least one and possibly as much as three are in simultaneous use. It's a great experience. (Do note that Schiphol does not supply Avgas 100LL anymore though.)
