Pa made some significant changes to the Health Care Power of Attorney statute which became effective in January, 2007. The new law did not invalidate prior documents, but you will not get the full benefit of the new statute if you do not update your document. I do not know how you came to the conclusion that getting a new Health Care Power of Attorney and General Power of Attorney would be very costly. You need to sit down with an attorney that primarily does estate planning and estate administration and discuss the pros and cons of updating your existing documents. Generally this will include a review of your existing documents and a discussion about whether any change is needed.

This site should not be used as a substitute for competent legal advice from a licensed attorney that practices in the subject area in your jurisdiction, who is familiar with your specific facts and all of the circumstances and with whom you have an attorney client relationship. The law changes frequently and varies from jurisdiction to jurisdiction. The information and materials provided are general in nature, and may not apply to a specific factual or legal circumstance described in the question or omitted from the question.
I agree that your current health care power of attorney is likely still at least marginally adequate, and that getting a replacement POA should not be an expensive proposition. The best thing for you to do would be to contact your county bar association to get a referral for a low-cost (generally around $25) or free consultation where an attorney who handles estate matters could review you documents and let you know whether any changes would be advisable. In any event, your financial POA shouldn't be affected, since the change in the law was specifically related to health care POAs.
Of course, as with all of my online answers, my advice is limited by the brevity of your question and the facts provided. Additional information would be required to provide definitive legal advice, so this answer isn't intended to, and does not, create an attorney-client relationship.
