How to let the user choose the number of nodes to display per page in a view

Here is the deal. I created to view to display available vacancies (custom CCK type) on my website. I have some exposed filters so that users could limit their seach queries. BUT! I need to have the ability to let user choose how many results per page he wants to get. Right now I only can set it in the view edit page, and it will be a fixed value. I tried using the argument handling code so that if there is a number in the url after view's name, this number will be used as a $limit, but here the problem is that exposed filters don't respect this manually added value and after user uses the exposed filters he is returned to the defaul view without the argument before.

So - I need help!

Thank you in advance.
